Abstract No. 291 The Interventional Radiology Match: A Bibliometric Analysis of 457 First-Year Residents

Bibliometric analysis has been established as a reliable method for quantifying research productivity. This study aims to conduct a bibliometric analysis to evaluate the significance of scholarly activity in a successful interventional radiology match. All integrated interventional radiology programs that are accredited by the Accreditation Counsil for Graduate Medical Education (ACGME) were identified. Various sources were queried, including residency program websites and personal and residency social media profiles, to compile a comprehensive dataset of first-year residents in Interventional Radiology who matriculated between 2020-2021 and 2022-2023. Resident research articles published by the time of match applications were collected, and bibliometric variables (e.g., publication count, h-index, journal impact factors, m-index) were extracted, primarily using the research database Scopus. Residencies were categorized according to residency program size. 457 residents who matriculated into an integrated interventional residency program between 2020-2021 and 2022-2023 were included in this retrospective study. Several key findings were demonstrated, including the research productivity of matched residents, Matriculated residents published an average of 2.1 ± 0.17 manuscripts per resident during their pre-residency period. Of the 977 research publications included, 216 (22%) were interventional radiology (IR) related, 266 (27%) were first authored, and 697 (71%) were original research articles. The average h-index per resident was 1.48 ± 0.10, and the average journal impact factor was 6.93 ± 0.37. There was a noteworthy trend toward correlation between h-index and matriculating into a larger size residency programs (p=. 0.56) and collinearity with number of publications. Factors contributing to increasing H index included journal impact factor, years since publication, and first authorship. Interestingly, IR-related manuscripts also correlated significantly with h-index. Interventional radiology research productivity showcases a commitment to academic excellence and innovation, which is reflected in the characteristics and patterns among first-year residents matched into Interventional Radiology residencies.
